Abstract
Techniques for routing network traffic in a storage processor involve providing per-IP routing tables for each IP address of a virtual server and a per-server routing table. These per-IP and per-server routing tables specify its own interface(s) with external network(s). The storage processor assigns each outbound protocol data unit (PDU), generated by a particular virtual server, to either a per-IP routing table or a per-server routing table provided for that virtual server. The assignment of the routing table is based on source IP address or a connection mark associated with an outbound PDU. The per-IP or per-server routing table(s) identifies an interface through which the packet is routed to the destination IP address.
